+CAD engine and post-processor.  Its design goal is to provide a fast, light
+and user-friendly meshing tool with parametric input and advanced
+visualization capabilities.  Gmsh is built around four modules: geometry,
+mesh, solver and post-processing.  The specification of any input to these
+modules is done either interactively using the graphical user interface or in
+ASCII text files using Gmsh's own scripting language.")
